Yep , i used one of my 4 free drinks to get fresh squeezed OJ in the dining room at breakfast .
Had a couple of drinks and used the rest for bottled water at cafe promenade .
You can use them for specialty coffee also . ( if you dont want a trip down to the D lounge )
Between the two of us , we had plenty of water and they chilled quite nicely in the room fridge.
The Diamond benefit is quite generous , over 400.00 USD per week , per person if you factor in a few coffees from the Diamond lounge every day along with 4 alcoholic drinks .
